Full textAbstract:
Digital literacy is a term that traditionally describes the extent to which a person is able to use interactive digital devices for living and working, such as computers and smartphones, as well as services delivered through these devices. The advent of the digital society at large and electronic business, specifically in the past decades, has broadened the use of digital devices beyond the isolated uses of working and simple communication; this advent has created digital ecosystems in which workers and consumers are embedded to various degrees, such as social media platforms or integrated shopping and media platforms. This embedding implies that a traditional, narrow notion of digital literacy needs to be extended and made more precise. For this purpose, we use the related notions of digital dexterity, digital proficiency and digital awareness. The term digital dexterity describes the extent to which an individual can handle or operate digital devices or services from a physical perspective. The term digital proficiency describes the extent to which an individual can use digital means to effectively and efficiently facilitate their living and working. The term digital awareness describes the extent to which individuals can understand what their position in digital ecosystems is, including the opportunities and threats of participating in these ecosystems. Digital literacy in the modern, broad interpretation is then the combination of digital dexterity, digital proficiency and digital awareness.

As performant and well-established as conventional silicon-based electronics have become, the era of wearable electronics and the Internet-of-Things has created a demand for robust electronic devices that can conform to the surfaces of the human body. Whereas the mechanical mismatch between rigid silicon electronics and the human body represents a fundamental limit to conventional non-invasive health sensing, wearable electronics and electrodes that can conform to the microscopic features of the skin1,2 can circumvent most of the motion artifacts inherent to conventional, rigid sensing devices, and facilitate continuous health monitoring as is required for modern, more proactive healthcare. Unfortunately, without addressing this fundamental mechanical incompatibility, devices that leverage the high density of transistors available in rigid silicon-based integrated circuits are handicapped by how well they can maintain contact with the body, and consequently are prone to failure at the sensor-circuit interface. The extraordinary properties of two-dimensional materials pose a unique opportunity for addressing this mechanical mismatch. Their unusual mechanical strength combined with their ultimate thinness, optical transparency, and favorable electronic transport properties3 makes them ideal candidates for the next generation of highly conformable wearable electronics free of the constraints of a rigid silicon circuit board—however, minimizing local strain in the vicinity of the active devices to ensure reliable operation remains a priority. Using a design informed by finite element method (FEM) simulations, our proposed strain-neutralizing 2D transistors are configured to resist applied strains on the order of the 30% strains human skin can withstand by redistributing strain away from active regions. Tight binding simulations of the transistor channels helps with further compensation of residual strain in the active regions, alongside careful consideration of materials and device architecture during fabrication. Together, these considerations help realize the possibility of fully integrated strain-neutralized 2D transistors compatible with state-of-the-art conformable wearable sensors. [1]S.

Full textAbstract:
Building on anthropologist Mary Douglas’s writing on the ritual function of dirt, this article presents a strategy in digital performance art that engages with electronic waste (e-waste). It is suggested that planned obsolescence in electronics is of a particular nature that facilitates the representation of consumer technologies within the logic of a “symbolic order of technological progress,” where digital devices act as mere signifiers for abstract notions of connectivity, well-being and innovation. Conceptualizing discarded electronic devices as abject technology that is positioned outside this symbolic structure, a performance practice is proposed where abject body parts and abject technologies are connected to challenge this techno-ideology.

Flexible and wearable electronics have recently emerged as a potential solution for next-generation electronics for healthcare, sports, transport, military, soft robotics, artificial intelligence, the internet of things, and other applications. However, these devices are still at a fledgling stage due to the use of traditional manufacturing processes, lack of compatible power supply, poor commercialization capabilities, and integration problems. Here, we present 3D printing approaches for developing batteries and supercapacitors for flexible electronic applications. Such manufacturing techniques can revolutionize the rapidly growing field of flexible and wearable electronics due to their several attributes like; rapid production, simplicity, capability to produce size and shape versatile patterns, computer-aided design, user control, and environmental friendliness.(1-4) Different aspects of 3D printed supercapacitors (such as; device design, ink preparation of electrode/ electrolyte components, rheology control of inks, surface modification to get good print quality, electrochemical performance of printed devices, and flexibility analysis) will be discussed in detail with a focus on future requirements.

Full textAbstract:
Although soft devices (grippers, actuators, and elementary robots) are rapidly becoming an integral part of the broad field of robotics, autonomy for completely soft devices has only begun to be developed. Adaptation of conventional systems of control to soft devices requires hard valves and electronic controls. This paper describes completely soft pneumatic digital logic gates having a physical scale appropriate for use with current (macroscopic) soft actuators. Each digital logic gate utilizes a single bistable valve—the pneumatic equivalent of a Schmitt trigger—which relies on the snap-through instability of a hemispherical membrane to kink internal tubes and operates with binary high/low input and output pressures. Soft, pneumatic NOT, AND, and OR digital logic gates—which generate known pneumatic outputs as a function of one, or multiple, pneumatic inputs—allow fabrication of digital logic circuits for a set–reset latch, two-bit shift register, leading-edge detector, digital-to-analog converter (DAC), and toggle switch. The DAC and toggle switch, in turn, can control and power a soft actuator (demonstrated using a pneu-net gripper). These macroscale soft digital logic gates are scalable to high volumes of airflow, do not consume power at steady state, and can be reconfigured to achieve multiple functionalities from a single design (including configurations that receive inputs from the environment and from human users). This work represents a step toward a strategy to develop autonomous control—one not involving an electronic interface or hard components—for soft devices.

Аннотация. В статье констатируется тот факт, что категория «Информация» является одной из самых дискуссионных в истории науки и философии. В XX веке появился новый вид информации — компьютерная (электронная, цифровая, машинная и т. д.). Применительно к объекту электронной цифровой криминалистики рассматриваются вопросы точного определения понятия информации, циркулирующей в компьютерных системах, сетях и иных электронных устройствах. Объектом электронной цифровой криминалистики являются как раз общественные отношения, связанные с собиранием, исследованием и использованием электронной цифровой информации и информационно-технологических устройств. Предметом электронной цифровой криминалистики полагаем закономерности возникновения, движения, трансформации криминалистически значимой электронной информации, закономерности оценки и использования криминалистически значимой электронной цифровой информации.В статье анализируются различные мнения относительно правильного наименования данной информации, определяются их положительные и отрицательные стороны. По результатам анализа различных подходов к рассматриваемой информации констатируется, что оптимальным для целей практической правоохранительной деятельности является определение «электронная цифровая информация», как отражающая и способ записи и своеобразный «язык» записи. Характеристика «электронный» говорит в первую очередь о способе записи, изменения, чтения и удаления с помощью движения электронов, электро-магнитных взаимодействий. Характеристика «цифровой» — о языке записи путем дискретизации аналоговой информации и представления ее в виде, как правило, дуальной последовательности цифр.При этом для раскрытия сущности данного вида информации необходимо указание на способ записи информации, форму записи, ее размещение и функциональное предназначение.По результатам исследования делается вывод о том, что электронную цифровую информацию можно определить как информацию, зафиксированную любым способом, но трансформируемую в человекочитаемый вид с помощью электромагнитных взаимодействий и кодированную с использованием цифрового кода, пригодную для автоматической обработки, находящуюся в информационно-технологических устройствах и передаваемую между ними любым способом либо распределенную между ними.Безусловно, активная разработка вопросов, связанных с электронной цифровой информацией в криминалистике, будет способствовать расширению информации о преступлении, переводимой из потенциальной криминалистически значимой в актуальную. Abstract. The article states that the category "Information" is one of the most controversial in the history of science and philosophy. In the 20th century, a new type of information appeared — computer (electronic, digital, machine, etc.). In relation to the object of electronic digital forensics, the issues of precise definition of the concept of information circulating in computer systems, networks and other electronic devices are considered. The object of electronic digital criminalistics is precisely social relations related to the collection, research and use of electronic digital information and information technology devices. The subject of electronic digital forensics, we consider the patterns of occurrence, movement, transformation of criminally significant electronic information, patterns of evaluation and use of criminally significant electronic digital information.The article analyzes various opinions regarding the correct naming of this information, identifies their positive and negative sides. According to the results of the analysis of various approaches to the information under consideration, it is stated that the optimal definition for the purposes of practical law enforcement is the definition of “electronic digital information” as reflecting both the method of recording and a kind of “language” of recording. The characteristic “electronic” speaks primarily about the method of writing, changing, reading and deleting using the movement of electrons, electro-magnetic interactions. The characteristic of “digital” is about the language of recording by sampling analog information and presenting it in the form, as a rule, of a dual sequence of digits.At the same time, in order to disclose the essence of this type of information, it is necessary to indicate the method of recording information, the form of recording, its placement and functional purpose.According to the results of the study, it is concluded that electronic digital information can be defined as information recorded in any way, but transformed into a human-readable form using electromagnetic interactions and encoded using a digital code, suitable for automatic processing, located in information technology devices and transmitted between them in any way, or distributed between them.Of course, the active development of issues related to electronic digital information in criminology will contribute to the expansion of information about the crime, translated from potential criminally significant to relevant.

Full textAbstract:
Flexible electronic systems have received increasing attention in the past few decades because of their wide-ranging applications that include the flexible display, eyelike digital camera, skin electronics, and intelligent surgical gloves, among many other health monitoring devices. As one of the most widely used technologies to integrate rigid functional devices with elastomeric substrates for the manufacturing of flexible electronic devices, transfer printing technology has been extensively studied. Though primarily relying on reversible interfacial adhesion, a variety of advanced transfer printing methods have been proposed and demonstrated. In this review, we first summarize the characteristics of a few representative methods of transfer printing. Next, we will introduce successful demonstrations of each method in flexible electronic devices. Moreover, the potential challenges and future development opportunities for transfer printing will then be briefly discussed.

Full textAbstract:
Consumers are keeping their electronic devices longer today than in the past because the prices of the devices have increased. Increased prices have culminated in more consumers needing their devices repaired. In turn, manufacturers use the Digital Millennium Copyright Act, a federal law, and digital rights management to force consumers to get their devices repaired by either the device manufacturer or one of its authorized repairers. In response, states have considered right-to-repair laws which require manufacturers to make repair tools, equipment, and software available to device owners and independent repair shops. While almost half of the country’s state legislatures have considered these bills, no state has enacted one fearing that the Digital Millennium Copyright Act will preempt any state’s action on the issue. Critics of these bills argue that the bills conflict with federal law, and therefore, federal law preempts right-to-repair laws. However, this Article argues that the Digital Millennium Copyright Act would not preempt a state’s right-to-repair law.

Beilstein Journal of Nanotechnology 5 (September 17, 2014): 1569–74. http://dx.doi.org/10.3762/bjnano.5.168.
Full textAbstract:
The performance of field effect transistors comprised of a zigzag graphene nanoribbon that is symmetrically doped with boron nitride (BN) as a channel material, is numerically studied for the first time. The device merit for digital applications is investigated in terms of the on-, the off- and the on/off-current ratio. Due to the strong effect of the substrate roughness on the performance of graphene devices, three common substrate materials (SiO2, BN and mica) are examined. Rough surfaces are generated by means of a Gaussian auto-correlation function. Electronic transport simulations are performed in the framework of tight-binding Hamiltonian and non-equilibrium Green's function (NEGF) formalisms. The results show that with an appropriate selection of the substrate material, the proposed devices can meet the on/off-current ratio required for future digital electronics.

Full textAbstract:
This study proposed a fabrication method for thin, film-based, transparent, and flexible digital microfluidic devices. A series of characterizations were also conducted with the fabricated digital microfluidic devices. For the device fabrication, the electrodes were patterned by laser ablation of 220 nm-thick indium tin oxide (ITO) layer on a 175 μm-thick polyethylene terephthalate (PET) substrate. The electrodes were insulated with a layer of 12 μm-thick polyethylene (PE) film as the dielectric layer, and finally, a surface treatment was conducted on PE film in order to enhance the hydrophobicity. The whole digital microfluidic device has a total thickness of less than 200 μm and is nearly transparent in the visible range. The droplet manipulation with the proposed digital microfluidic device was also achieved. In addition, a series of characterization studies were conducted as follows: the contact angles under different driving voltages, the leakage current density across the patterned electrodes, and the minimum driving voltage with different control algorithms and droplet volume were measured and discussed. The UV–VIS spectrum of the proposed digital microfluidic devices was also provided in order to verify the transparency of the fabricated device. Compared with conventional methods for the fabrication of digital microfluidic devices, which usually have opaque metal/carbon electrodes, the proposed transparent and flexible digital microfluidics could have significant advantages for the observation of the droplets on the digital microfluidic device, especially for colorimetric analysis using the digital microfluidic approach.

Traditional notice boards are very difficult to maintain and involves very tedious process to change notice every time. This also is accompanied by waste of paper, ink, time, and manpower as well. This research work presents a low-cost new concept of digital wireless electronic notice board based on Global System for Mobile communications (GSM) modem whereby the required notice to be displayed will be sent through Short Message Service (SMS). This transmission of information is done by Radio Frequency wireless technique. In this device, a message or notice is sent to the display device like Liquid Crystal Display (LCD), and this message can be easily modified and sent from any part of the world, just by using the SMS facility in GSM cellular devices. Whatever notice to be displayed on the board is sent using suffix and prefix, and the message sent is displayed on the 16*2 display built on the wireless notice board. This work is very useful in schools, cinema halls, railway stations, colleges, offices etc. where the notice can be changed from anywhere, at any moment and as many times it needs to be modified.

Background Globally, the rapid growth of technology and its use as a development solution has generated much interest in digital health. In line with global trends, Bangladesh is also integrating technology into its health system to address disparities. Strong political endorsement and uptake of digital platforms by the government has influenced the rapid proliferation of such initiatives in the country. This paper aims to examine the implications of digital health on access to health care in Bangladesh, considering who uses electronic devices to access health information and services and why. Objective This study aims to understand how access to health care and related information through electronic means (digital health) is affected by sociodemographic determinants (ie, age, gender, education, socioeconomic status, and personal and household ownership of mobile phones) in a semiurban community in Bangladesh. Methods A cross-sectional survey of 854 households (between October 2013 and February 2014) and 20 focus group discussions (between February 2017 and March 2017) were conducted to understand (1) who owns electronic devices; (2) who, among the owners, uses these to access health information and services and why; (3) the awareness of electronic sources of health information; and (4) the role of intermediaries (family members or peers who helped to look for health information using electronic devices). Results A total of 90.3% (771/854) of households (471/854, 55.2% of respondents) owned electronic devices, mostly mobile phones. Among these, 7.2% (34/471) used them to access health information or services. Middle-aged (35-54 years), female, less (or not) educated, and poorer people used these devices the least (α=.05, α is the level of significance). The lack of awareness, discomfort, differences with regular care-seeking habits, lack of understanding and skills, and proximity to a health facility were the main reasons for not using devices to access digital health. Conclusions Although influenced by sociodemographic traits, access to digital health is not merely related to device ownership and technical skill. Rather, it is a combination of general health literacy, phone ownership, material resources, and technical skill as well as social recognition of health needs and inequity. This study’s findings should serve as a basis for better integrating technology within the health system and ensuring equitable access to health care.

<span lang="EN-US">The rapidly increasing number of internet of things (IoT) and non-IoT devices has imposed new security challenges to network administrators. Accurate device identification in the increasingly complex network structures is necessary. In this paper, a device fingerprinting (DFP) method has been proposed for device identification, based on digital footprints, which devices use for communication over a network. A subset of nine features have been selected from the network and transport layers of a single transmission control protocol/internet protocol packet based on attribute evaluators in Weka, to generate device-specific signatures. The method has been evaluated on two online datasets, and an experimental dataset, using different supervised machine learning (ML) algorithms. Results have shown that the method is able to distinguish device type with up to 100% precision using the random forest (RF) classifier, and classify individual devices with up to 95.7% precision. These results demonstrate the applicability of the proposed DFP method for device identification, in order to provide a more secure and robust network.</span>

Full textAbstract:
The easy access to electronic devices for users has resulted in the development of a vast range of programs and applications for visual evaluation and diagnosis that can be downloaded to any device. Some of them are based on tasks and stimuli that depend on luminance. The aim of the present study was to evaluate differences in luminance reproduction between electronic devices and their implications for contrast reproduction. A total of 20 Galaxy Tab A devices with 8-bit graphics processing units were evaluated. Characterization of every screen was performed obtaining the response curve for the achromatic stimulus. Mean, maximum and minimum luminance, standard deviation and coefficient of variation were obtained to assess differences between devices. Variation of luminance with increasing digital level was observed in all devices following a gamma distribution. Comparison between devices for mean results showed that some of them differed by as much as 45 cd/m2. The coefficient of variation varied from ~5 to 9%. Mean percentage of differences in luminance between devices reached 30%. In conclusion, differences in luminance reproduction between devices were present, even considering devices from the same manufacturing batch. It cannot be assumed that the characterization of one device can be extrapolated to other devices. Every device used for research purposes should be individually characterized to ensure the correct reproduction. For clinical purposes, limitations should be considered by visual specialists.

This paper concerns the use of electrical capacity in the measurement of force and torque as an alternative to conventional strain gauges. It has been established that for some requirements mechanical configurations can be designed with integrated capacitor bridges which combine a good performance with low cost and compactness. Simple electronic circuitry incorporating multiplexing has been developed and used to drive multi-axis devices. Examples include a configuration for measuring the three torques at a point. Work on an integrated circuit shows the possibility of positioning the electronics within a device with a serial digital interface to a host computer.

This paper introduces a miniaturized personal electronic nose (39 mm × 33 mm), which is managed through an app developed on a smartphone. The electronic nose (e-nose) incorporates four new generation digital gas sensors. These MOx-type sensors incorporate a microcontroller in the same package, being also smaller than the previous generation. This makes it easier to integrate them into the electronics and improves their performance. In this research, the application of the device is focused on the detection of atmospheric pollutants in order to complement the information provided by the reference stations. To validate the system, it has been tested with different concentrations of NOx including some tests specifically developed to study the behavior of the device in different humidity conditions. Finally, a mobile application has been developed to provide classification services. In this regard, a neural network has been developed, trained, and integrated into a smartphone to process the information retrieved from e-nose devices.

The paper draws attention to the intensification of criminal use of electronic technology, on the one hand, and the digitalization of forensic activities to investigate crimes, on the other hand. It is stated that it is necessary to develop a unified concept of electronic digital criminalistics. The paper analyzes the views on the essence of this concept and similar concepts of other scientists. The ideas of allocating a new branch, section or subsection in criminology are subject to reasonable criticism.Investigating the main opinions of scientists on the criteria for distinguishing private theories in criminology, the author concludes that the private theory of electronic digital criminology (detection, fixation, seizure, research and use of electronic information and information technology devices) fully meets the basic requirements for private forensic theories. Regarding the place of the considered private theories in the criminology we can see justified criticism of the private placement of this theory in the section "Forensic engineering", and the distinction between two individual theories that are, respectively, technical and tactical in nature. The author states that the conceptual issues of the private theory of electronic digital criminology (collection, research and use of electronic digital information and information technology devices) should be considered in the section "General theory of criminology".The paper discusses in detail the place of this particular theory in the system of other private theories of criminology and its relationship with them, as well as its relationship with other sciences, primarily with cybernetics and computer science, information law, criminal procedure, the theory of evidence, the theory of operational investigative activities, forensic expertise, general, legal and cybernetic linguistics.

Full textAbstract:
Thin-film electronics intimately laminated onto the skin imperceptibly equip the human body with electronic components for health-monitoring and information technologies. When electronic devices are worn, the mechanical flexibility and/or stretchability of thin-film devices helps to minimize the stress and discomfort associated with wear because of their conformability and softness. For industrial applications, it is important to fabricate wearable devices using processing methods that maximize throughput and minimize cost. We demonstrate ultraflexible and conformable three-color, highly efficient polymer light-emitting diodes (PLEDs) and organic photodetectors (OPDs) to realize optoelectronic skins (oe-skins) that introduce multiple electronic functionalities such as sensing and displays on the surface of human skin. The total thickness of the devices, including the substrate and encapsulation layer, is only 3 μm, which is one order of magnitude thinner than the epidermal layer of human skin. By integrating green and red PLEDs with OPDs, we fabricate an ultraflexible reflective pulse oximeter. The device unobtrusively measures the oxygen concentration of blood when laminated on a finger. On-skin seven-segment digital displays and color indicators can visualize data directly on the body.

The roots, stems, leaves, and vascular circuitry of higher plants are responsible for conveying the chemical signals that regulate growth and functions. From a certain perspective, these features are analogous to the contacts, interconnections, devices, and wires of discrete and integrated electronic circuits. Although many attempts have been made to augment plant function with electroactive materials, plants’ “circuitry” has never been directly merged with electronics. We report analog and digital organic electronic circuits and devices manufactured in living plants. The four key components of a circuit have been achieved using the xylem, leaves, veins, and signals of the plant as the template and integral part of the circuit elements and functions. With integrated and distributed electronics in plants, one can envisage a range of applications including precision recording and regulation of physiology, energy harvesting from photosynthesis, and alternatives to genetic modification for plant optimization.

Abstract The ability to place atoms one by one at specific atomic sites was first used to create functioning electronic devices in the late 1990s. Since then, the process known as atomic precision advanced manufacturing (APAM) has been further developed and both academic and commercial interest in its potential has grown. This article describes the nuances of the process, explaining that it places dopants into silicon using surface chemistry, a mechanism not typically used in microfabrication. It also discusses ongoing efforts to develop more complex quantum devices using APAM techniques and outlines the challenges involved in interfacing APAM and CMOS devices on the same die.

Full textAbstract:
Getter materials are technically proven and industrially well-implemented solutions for maintaining a vacuum inside electronic devices to assure long lifetimes and proper operating conditions. The pressure requirements of some hermetically packaged microelectromechanical systems (MEMS) devices, such as gyroscopes, accelerometers, infrared (IR) bolometers, and digital mirrors, are very stringent. The internal pressure can be as low as in the 10−3 mbar range. Due to the desorption phenomena of gaseous species from the internal surfaces, the vacuum inside such hermetically sealed electronic devices tends to degrade over time and, in the worst case, can affect the proper operation of the device. The integration of a special nanostructured getter film is an effective way to preserve and guarantee the performance of such devices. In addition to the getter material, there is also the need to develop and customize analytical techniques for post-process vacuum quality control and reliability checks of hermetic bonding, which are extremely important for the assessment of a device’s overall performance, lifetime, and manufacturing process yield.

A1N, GaN, and InN are very promising materials for use in optoelectronic and high-temperature electronic devices. These materials and their ternary and quaternary alloys cover an energy bandgap range of 1.9–6.2 eV, suitable for band-to-band light generation with colors ranging from red to ultraviolet (uv), with wavelengths ranging from 650 to 200 nm. On the device front, they are suitable for example for negative electron-affinity cold cathodes, electronic devices, surface acoustic wave devices, uv detectors, Bragg reflectors and waveguides, uv and visible light-emitting diodes (LEDs), and laser diodes (LDs) for digital data read-write applications. Stifled by the absence of native substrates, growth and doping of high-quality III-V-nitride thin films, particularly p-type, have been major obstacles for developing GaN-based devices. Development of electronic devices such as modulation-doped field-effect transistors (MODFETs) and opto-electronic devices such as LEDs and LDs has also proven challenging.

Full textAbstract:
Class D power amplifiers, one of the most critical devices for application in sound systems, face severe challenges due to the increasing requirement of smartphones, digital television, digital sound, and other terminals. The audio power amplifier has developed from a transistor amplifier to a field-effect tube amplifier, and digital amplifiers have made significant progress in circuit technology, components, and ideological understanding. The stumbling blocks for a successful power amplifier are low power efficiency and a high distortion rate. Therefore, Class D audio amplifiers are becoming necessary for smartphones and terminals due to their power efficiency. However, the switching nature and intrinsic worst linearity of Class D amplifiers compared to linear amplifiers make it hard to dominate the market for high-quality speakers. The breakthrough arrived with the GaN device, which is appropriate for fast-switching and high-power-density power electronics switching elements compared with traditional Si devices, thus, reducing power electronic systems’ weight, power consumption, and cost. GaN devices allow Class D audio amplifiers to have high fidelity and efficiency. This paper analyzes and discusses the topological structure and characteristics and makes a judgment that Class D amplifiers based on GaN amplifiers are the future development direction of audio amplifiers.

Abstract Cryptography is a field of science necessary to solve problems with encryption of classified messages. The security of electronic information is an integral part of the digital tachography system. From year to year, there is a noticeable increase in electronic data logging systems in many aspects of life. The control measures created for the purpose of performing roadside checks are not sufficient to detect all violations in the recording equipment. Many violations that have occurred during the use of the vehicle are stored in the device’s memory. The article describes the basic mathematical rules illuminating cryptography. The hazards to which the motion sensor installed in the vehicle may be exposed are described. Breaking safety in transport systems may lead to incorrect results of inspections carried out while the vehicle is stopped by authorized services. The article also provides information on the authorities responsible for issuing cards for digital tachographs. Nowadays, documents are increasingly issued with the use of a digital signature. The digital signature of its origin is based on the principles of cryptography. The security key seems to be complicated for the average user. The article discusses the topic of tachograph construction, in particular the schematic responsible for information encryption.

Full textAbstract:
Substations are becoming increasingly reliant on international electrotechnical commission (IEC)-61850-enabled devices. However, device compatibility with these standards does not guarantee interoperability when devices are taken from different manufacturers. If interoperability of multivendor devices can be achieved, then power utilities will be in a position to implement multivendor devices in substations. The study here presents the development and testing of a digital substation test platform that incorporates devices from different manufacturers. The process bus communication and protection operation of the intelligent electronic devices (IEDs) were tested to validate device interoperability. The testbed was tested for two IED process bus communications, generic object-oriented substation event (GOOSE) and sampled measured value (SMV). The GOOSE is travelling between IED to IED with an end-to-end (ETE) delay of 2 ms and the SMV read by the IEDs are the same as the injected real-time substation inputs 220 kV and 1 kA. Three IED protection studies (overcurrent, earth fault, and overvoltage) were performed, and IED response curves were obtained. In addition, data monitoring and client–server communications were studied using installed software tools. The testbed configuration in this study has faced some real-time challenges regarding differences in device edition, device firmware, and ethernet switch due to its multivendor approach. All the mentioned configuration issues were resolved in this study with successful testing and validation of the testbed. The study of this testbed will provide solutions to the problems associated with a multivendor system faced by substation engineers and will help them in opting for multivendor installations. This system can be extended in the future by installing more multivendor devices with complex network topology and a SCADA system.

Digital printing technologies are becoming increasingly important for modern electronics production. Besides inkjet printing for low viscosity inks, jetting of pasty materials such as PTF can be a viable alternative to traditional subtractive or additive metallization methods in the future. Hybrid printed electronics, a combination of printed circuitry with classical electronic components, offers many advantages such as low cost, environmental sustainability and others. Until now, the mechanical and electrical properties of printed pastes on molded substrates have not been investigated in detail, just as little as the long-term characteristics of interconnection technologies necessary to mount traditional electronic components onto printed substrates. In different test series, electrical resistance and adhesion of a special PTF material have been investigated. The long-term behavior of the material itself and three alternative interconnection technologies for mounting of SMT components has been evaluated. Results are encouraging, although still a lot of improvements are necessary.

Electronics Practicum in the Laboratory is a routine activity carried out to support student skills. Capacitors are one of the components that are often used in practice. Capacitors are one of the passive electronic components that have a magnitude value in the form of capacitance in Farad units. The capacitance value indicates the capacitor's ability to store electric charge. However, the value contained on the capacitor label is not necessarily the actual value because the capacitor has a tolerance range. Of course, this is very influential in the measurement and performance of electronic circuits that use capacitors. In addition, another factor that supports this research is that the available measuring instruments, such as the multimeter, are not yet equipped with capacitance measurements. Capacitance meters available in the market are still analog. The purpose of this study is to design a device that can measure the capacitance value of capacitors as a measurement device in a digital laboratory, namely the Digital Capacitance Meter. This device is made using Arduino Uno as a microprocessor for data processing. The method used is to apply the process of charging and discharging the capacitor. In this case, Arduino Uno activates a timer to measure the time required to charge and discharge the capacitor so that the Time Constant value is obtained. By using the formula T = 0.693RC, the capacitance value can be obtained. In testing using 3 different capacitors and 10 times testing on each capacitor, the accuracy of the device is 97.76% and a relative error of 2.24%.

Full textAbstract:
New smartphones made by small companies enter the technology market everyday. These new devices introduce new challenges for mobile forensic investigators as these devices end up becoming pertinent evidence during an investigation. One such device is the PinePhone from Pine Microsystems (Pine64). These new devices are sometimes also shipped with OSes that are developed by open source communities and are otherwise never seen by investigators. Ubuntu Touch is one of these OSes and is currently being developed for deployment on the PinePhone. There is little research behind both the device and OS on what methodology an investigator should follow to reliably and accurately extract data. This results in potentially flawed methodologies being used before any testing can occur and contributes to the backlog of devices that need to be processed. Therefore, in this paper, the first forensic analysis of the PinePhone device with Ubuntu Touch OS is performed using Autopsy, an open source tool, to establish a framework that can be used to examine and analyze devices running the Ubuntu Touch OS. The findings include analysis of artifacts that could impact user privacy and data security, organization structure of file storage, app storage, OS, etc. Moreover, locations within the device that stores call logs, SMS messages, images, and videos are reported. Interesting findings include forensic artifacts, which could be useful to investigators in understanding user activity and attribution. This research will provide a roadmap to the digital forensic investigators to efficiently and effectively conduct their investigations where they have Ubuntu Touch OS and/or PinePhone as the evidence source.

Instrumental digital didactics reflects the application to education of various digital means of obtaining, processing and interpreting experimental data in accordance with the logic of the scientific method and engineering design. An important component of a modern STEM-oriented educational environment are innovative software products for modelling and simulation of electronic circuits. In educational research projects on their basis, the parameters of the components of electrical circuits created in virtual environments are compared with the technical characteristics of similar devices available for sale. This technique allows not only to demonstrate the similarities and differences of idealized and real artifacts, to identify sources and magnitude of possible errors, but also to obtain electrical characteristics sufficient to build equivalent schemes for substituting devices without prior experimental research. The proposed approach is demonstrated on the example of studying the parameters of a device of current interest — a photoelectric converter (determining the point of its maximum power and the fill factor). Learning by means of using equivalent substitution schemes demonstrates one of the variants of the engineering design process to students. In addition, the proposed method, due to the possibility of development from an algorithmic training procedure to an engineering research, allows for an individual approach to the teaching of electrical engineering and electronics. Research of didactic features of the study of electricity and the basics of electronics, in particular with the use of NI “Multisim 11.0”, is one of the activities of the STEM-laboratory of “MANLab” National centre “Junior academy of sciences of Ukraine”. Some of the tested methods are designed as a workbook and placed in free access in the form of instructions on the online resource stemua.science.

Abstract A memristor is a new electronic device with small volumes and small fluctuations. As a two-terminal device, it is mainly characterized by non-volatility and nanoscale characteristic size. Memristors can also calculate and store at the same time, which has a broad application prospect in logic circuits. Traditional integrated circuit technology has been very mature. And CMOS technology has almost reached the limit of physical size. Compared with traditional circuit components, memristor devices are compatible with CMOS circuits with their fast computing speed, low power consumption, and small layout area. A three-state output module based on a threshold memristor is proposed. The structure includes an inverter, a PMOS tube, two NMOS tubes, and two threshold memristors. Compared with the traditional three-state gate which only uses CMOS technology, the circuit area required by the module is smaller and the overall power consumption is lower, which caters to the development trend of portable and low-power electronic devices. Then the digital switch circuit using this module is introduced, which provides a new idea for the data transmission circuit. The circuit and module are simulated and verified by LTspice software.
